Abstract
A saw assembly for a grip-harvester has a saw chain (4) running around a bar (3) and a chain sprocket (5); a bar holder (2) pivotably journalled on the saw assembly stand (1); a saw motor (6) driving the chain sprocket (5); and a device (14) for feeding the bar out and in, said feeding-out and feeding-in device (14) comprising a hydraulic cylinder (17) mounted on the stand (1) and having a piston rod (19). According to the invention the movements of the piston rod (19) are transmitted to the pivotable bar holder by means of a pivotably journalled toothed wheel (26) which is joined to the bar holder (2) and has a toothed wheel rim (27) cooperating with the piston rod which is in the form of a rack. The saw assembly is also provided with a device for sensing and recording the angular position of the saw bar (3) in relation to an initial position, which device has a smaller toothed wheel (60) in engagement with the larger toothed wheel (26) of the feeding-out and feeding-in device (14), and also a sensor (61 or 62) which senses a tooth gap or a tooth on said smaller toothed wheel (60).
